From the foregoing, it will be seen that there has been provided an improved grass catcher, and in use with the parts arranged as shown in the drawings, the grass catcher 36 of the present invention can be readily attached to a conventional lawn mower, such as the power operated lawn mower 30.

' Initially, the

members

37 and 38 may be formed as shown in H6. 6. Then, when it is desired to assemble the device, a member such as the member 37 will have its

portions

53, 54, 55, 56 and 57, as well as the other associated parts, folded along the respective crease or fold lines so that the completed unit 36 is provided,

which has a hollow construction. Each of the units or

members

37 and 38 has a generally one piece self supporting, non-internally or externally braced construction, and the various flaps or tongues are adapted to interfit in the respective slots or other parts so that the units will be maintained in their proper assembledposition.

Thus, the tongue 66 is adapted to be snugly received in the groove or slot 73, while the tongue 77 is adapted to be received in the slot 76. The tongue 72 will be received in the slot 74, and the tongue 115 will be received in the slot 75 so that the parts will inter-fit and lock in the proper manner.

Similarly, when forming the unit 38, the

portions

86, 8, 90 and 92 are adapted to be inter-folded and interitted, and wherein the tongues 11] are snugly and firmly received in the slots 94 so that a completed unit 38 can be formed by folding the sections or portions along their respective crease or fold lines.

The rod 100 is adapted to have its transverse portion 102 extended through the registered

openings

110 and 78, and the end portion 106 of the filter 103 is held in place as shown in the drawings. The other end portion 104 of the filter cloth 103 is mounted on the portion 102 of the rod. The portion 101 of the rod 100 is held in place by means of securing elements 99.

With the parts arranged as shown in the drawings, and in particular as shown in FIGS. 2 and 3, for example, it will be seen that as the engine 34 of the lawn mower is operated, the grass, litter and the like, will be thrown out through the discharge chute 35, then through the opening 68 and into the interior of theunit 37. This mixture of air and grass or cuttings will then enter the zone or chamber 105, and due to the provision of the porous filter member 103, the air can pass upwardly through the filter 103 from the zone 105 to the zone 107, and this air can then be discharged out through the open space 108. When it is desired to empty the device 36, the parts can bepivoted to a position such as that shown in FIG. 8, so that the grass 39 will empty out from the device into the desired receptacle or the like. As shown in FIG. 8, the opening 68 provides a convenient handhold, so that the user can arrange the hand in engagement therewith to facilitate emptying of the device.

The connection between the

parts

48 and 41 is a detachable fitting so that when it is desired to remove the grass catcher from the lawn mower, the lugs 51 can be readily disengaged from the slots 47. However, when the grass catcher is being used on the lawn mower, the inter-fitting lugs 51 and slots 47 will provide a firm anchor for connecting the grass catcher to the lawn mower.

It is to be understood that the parts can be made of any suitable material and in different shapes or sizes, as desired or required.

As shown in the drawings, the front end of the grass catcher 36 is generally closed, and similarly, the rear end of the grass catcher is closed due to the interlocking and interfitting folded flaps or tongues. However, there is provided the opening 108 which permits air to discharge thereto in the desired direction. A fastener or nut 116 may be arranged in threaded engagement with the portion 102 of rod for maintaining the rod in its proper assembled position.

In FIG. 8, the numeral 117 indicates on eof the users hands that can grip an end of the device, while the other hand 109 is gripping in the vicinity of the opening 68.

As illustrated in the drawings, instead of the air blowing out through the rear of the grass catcher, the air discharges out through the opening 108 in the middle of the unit. With the present invention, it is not necessary to attach a grass catcher bag to a lawn mower, since the grass will be collected in the device of the present invention, and subsequently, this grass can be emptied into any desired location or receptacle.

It is to be understood that the particular embodiments of the invention described herein are merely illustrative of the underlying principles involved, and numerous other arrangements, modifications and adaptions may be conceived without departing from the spirit and scope of the invention.
